Displaced spiral and oblique fractures of the proximal phalanx are unstable and non-operative treatment frequently results in malunion. Such fractures are therefore treated operatively. No previous study has compared the two common techniques used.

Patients with an isolated spiral or oblique fracture of the proximal phalanx were prospectively randomised into two groups. One was treated by closed reduction and Kirschner wire fixation and the second treated by open reduction and lag screw fixation. An independent observer assessed function, pain, movement, grip strength and intrinsic muscle function. X-rays were assessed for malunion.

32 patients entered the study. At follow-up (mean 40 months) there were 15 in the Kirschner wire and 13 in the lag screw group. All returned to their normal employment and 18 described a full functional recovery. There was no significant difference in the functional recovery rates (Fischer exact test p=0. 3) or in pain scores for the two groups (median 0 for both). Radiographs showed similar rates of malunion and there was no statistically significant difference in range of movement or grip strengths.

This prospective randomised study has shown no significant difference in outcome for the two techniques. We would recommend that surgeons should choose the method with which they are most familiar and competent, or the technique that utilises the least health care resources.

This study investigates the role of pre-operative mental health on outcome following Total Knee Replacement.

Patients were recruited as part of a prospective, observational study of the outcomes of primary total knee replacement for osteothritis in centres in the United Kingdom (6 centres), United States (4 centres) and Australia (2 centres). Independent, research assistants recruited eligible patients, collecting clinical history and examination data pre-operatively, 3 and 12 month post surgery. The SF-36, WOMAC, patient satisfaction and demographic data were obtained by self-administered questionnaires.

We recruited 862 eligible patients and have completed 12-month data on 742 patients (86%). Mean age was 70 years (SD 10), 59% were female, 50% were from the UK, 30% from the USA and 20% from Australia. In linear regression models, the significant correlates of preoperative mental health (in decreasing order of significance) were: low preoperative WOMAC function (Std B 8, 2; p< 0. 0001), self reported depression (Std 8 7. 6; p< 0, 0001), female gender (Std 13 2. 9 p=0, 004), older age (Std 13 2, 9; p=0. 004), other comorbid conditions (Std 3 2. 8; p=0, 005) and low income (Std B 23; p-0, 03). 12 months following surgery, low pre-operative mental health was a significance predictor of worse WOMAC pain and function (p< 0. 0001). The linear regression models adjusted for preoperative pain and function, age, sex, comorbid conditions, country and centre within country. With the exception of the pre-operative WOMAC pain and function score, low pre-operative mental health was the strongest of worse outcome 12 months after TKR.

Low pre-operative mental health is a highly significant predictor of worse outcome one year after Total Knee Replacement. It may be possible to identify patients with poor mental health before surgery using the SF36 mental health score as well as self-reported depression. This may allow for effective treatment of their mental health problems prior to TKR and/or highlight the need for extra rehabilitation input to improve outcome following surgery.
